Yes, it will have so many characters. But not all of them will be seen doing activities in the city. For example, Ayune, her father, Mr. Kobayashi... these characters will only appear for missions. Multiple ending it planned. Depending on how a few questlines are progressed.
I might not do original 0.1-0.7 timelines. Respective girls will appear replacing the original one. But might do Rangiku or Rumei's story since I need to add something if Masuo rejects the ring.
That's not missing girl list. It's Ryoko's elimination list. She wants to make sure Masuo doesn't end marrying girl having red dot.
Their portrait will not be included in LSH. Here they are if you need them for later.
